% HOW TO PLAY - step by step
% 1. You are the RED archer (YOU, front lane). MATLAB is the BLUE archer (back lane). Both stand astride the white shooting line.
% 2. Shooting order: YOU, MATLAB, YOU, MATLAB ... 3 arrows each per set (a set = 6 arrows).
% 3. AIM: move the mouse. The green crosshair sits under your cursor on your target. It already includes the wind push,
%    so if the wind is +1.0 (to the right) the arrow drifts right: that is already shown, just place the crosshair on the spot you want.
% 4. DRAW: click once when the crosshair is where you want. The bow stretches (about 1 second). You may still fine-tune the aim.
% 5. TIMING SKILL: when the bow is fully drawn, a yellow marker swings along the bar at the top. Click again to release.
%    Click when the marker is inside the GREEN zone = arrow goes exactly to the crosshair. Clicking at the ends of the bar = arrow flies off to the side.
% 6. SCORE: the ring hit gives 10 (gold centre) down to 1 (outer white), 0 = MISS.
% 7. SET POINTS: the set winner gets 2 points, a tied set gives 1 point each.
% 8. END: first to 4 set points wins (can happen after the 2nd set). If nobody has 4, set 3 decides; equal points = DRAW.
% 9. After the match ends, click to play again.
